To what degree? Accuracy is great, but I think people are assuming that one will still have enough power to actually cause damage. Example: the accurate old west gunslinger was still shooting a .44 caliber! But a shot-gun may pack more of a wallop without the need to be as accurate.
Depending upon the range.... shot gun great in close quarter...revolver better at medium range... rifle best for max range.

comparing weapons like guns to hand to hand is a little over kill and not exactly accurate in depiction.
